Slight leaf curl - What's the cause and should I be worried!

[Apexsmoker420]

I noticed this slight leaf curl today should I be worried and what could be the cause!

It's possible the smaller plants are from overwatering because of the flushed soil when I transplanted. But the bigger plant hasn't been watered in 6 days today. I was planning on watering tonight but now I'm gonna hold off.

And input is greatly appreciated!!!

They don't look over watered in my opinion. I think they look fine at this point. Just double check air flow and humidity. Temps also. They look fine to me. Good luck with your grow.

Thank you

The leaves in that bottom shot look a little troubled, like maybe they've been getting over-intense light?

They look great. At this stage of the game a bit of PH'd water sprayed on the leaves is something they like in my experience.

I didn’t think about that. I do have the 600w MH lights pretty close do to the fact I’ve set the ventilation system up pretty nice so I’ve been able to keep temps low.

It seems like leaves that are at the top and right under the beam are most likely to get nuked, not surprisingly. It's not just temperature. Excessive photon bombardment can do it too.

Updated Pics:. They were fed their first round of nutes yesterday at 1/4 strenght GH foralseriesb + 3ml of calimagic

Looking good.

Looking good.

See I was thinking the opposite with the spots and yellowing on the lower leaves

The new growth all looks good though.

Taken yesterday this is the new symptom.



Also another plant just started getting underdeveloped and waxy looking leaves

Where was it on the plant? (Bottom, I'll bet.)

Yes the bottom

Yes the bottom

OK. Again, it really helps to see the leaves in place for context, not trimmings.

Have you ever given that plant any fertilizer? If not, it might be time to start thinking about that. When bottom leaves turn yellow, I believe it's often from a lack of nitrogen, a mobile nutrient that moves from older leaves to newer when it's in short supply.

This plant has had 2 feedings GH nutrients floralseries at 1/4 strenght the second feeding was a little higher. Also doing feed/water/feed/water. The full journal is in my signature.

I looked at your grow log. Nice setup!

I guess I'd suggest "watchful waiting" as they say in the medical business, and if you see more yellowing, consider increasing the dosages. Your plants look good!

Here you go bud lol

That's a good looking plant!

The fact that it's loosing the odd bottom leaf would seem to indicate to me that it wants a little more nitrogen, but I don't think it's anything to worry about.
